Describe the bug 🐞

Expected behavior

Elegant HTML output.

Minimal Reproducible Example 👇

begin
	using ModelingToolkit
	using ModelingToolkit: t_nounits as t, D_nounits as D
	using SymbolicIndexingInterface
	using DataInterpolations, ReadOnlyArrays
	using Symbolics
end

@parameters P_out[1:5]

P_out[1]

Environment (please complete the following information):

• Output of using Pkg; Pkg.status()

This is probably a Symbolics/SymbolicsUtils issue? Please move to the appropriate repository.

That's a Symbolics issue, though it's odd because that looks like proper latex?

[cstjean]

Not sure about proper latex, but FWIW

[ChrisRackauckas]

The wrong underscore?

[SebastianM-C]

Isn't it that you have 2 underscores instead of just one? I think that the { wrapping should cover the entire underscored argument.
